将JQuery Mobile和Phonegap一起使用的正确方法(截止日期)是什么？
两个框架都需要在可以使用之前加载.在使用它们之前,我怎么能确定它们都已加载？

您可以使用JQuery的延迟功能.
var deviceReadyDeferred = $.Deferred();
var jqmReadyDeferred = $.Deferred();
document.addEventListener("deviceReady", deviceReady, false);
function deviceReady() {
deviceReadyDeferred.resolve();
}
$(document).one("mobileinit", function () {
jqmReadyDeferred.resolve();
});
$.when(deviceReadyDeferred, jqmReadyDeferred).then(doWhenBothFrameworksLoaded);
function doWhenBothFrameworksLoaded() {
// TBD
}

基于上面的例子,这是它对我有用的方式
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />

</head>
<body>
<script type="text/javascript" src="js/jquery-1.8.3.js"></script>
<script type="text/javascript">
var dd = $.Deferred();
var jqd = $.Deferred();
$.when(dd, jqd).done(doInit);
$(document).bind('mobileinit', function () {
jqd.resolve();
});
</script>
<script type="text/javascript" src="js/jquery.mobile-1.2.0.js"></script>
<script type="text/javascript" src="cordova-2.2.0.js"></script>
<script type="text/javascript">
document.addEventListener('deviceready', deviceReady, false);
function deviceReady() {
dd.resolve();
}
function doInit() {
alert('Ready');
}
</script>
</body>
</html>
为了使用phonegap和jquery mobile,你需要像这样使用它
<head>
<title>Index Page</title>
<!-- Adding viewport -->
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, user-scalable=no">
<!-- Adding jQuery scripts -->
<script type="text/javascript" src="jquery/jquery-1.7.1.min.js"></script>
<!-- Since jQuery Mobile relies on jQuery core's $.ajax() functionality,
$.support.cors & $.mobile.allowCrossDomainPages must be set to true to tell
$.ajax to load cross-domain pages. -->
<script type="text/javascript">
$(document).bind("mobileinit", function() {
$.support.cors = true;
$.mobile.allowCrossDomainPages = true;
});
</script>
<!-- Adding Phonegap scripts -->
<script type="text/javascript" charset="utf-8"
src="cordova/cordova-1.8.0.js"></script>
<!-- Adding jQuery mobile scripts & CSS -->
<link rel="stylesheet" href="jquerymobile/jquery.mobile-1.1.0.min.css" />
<script type="text/javascript"
src="jquerymobile/jquery.mobile-1.1.0.min.js"></script>
</head>
<script type="text/javascript">
// Listener that will invoke the onDeviceReady() function as soon as phonegap has loaded properly
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
navigator.splashscreen.hide();
document.addEventListener("backbutton", onBackClickEvent, false); // Adding the back button listener
}
</script>
<body>
<div data-role="page" id="something" data-ajax="false">
<script type="text/javascript">
$("#something").on("pageinit", function(e) {
});
$("#something").on("pageshow", function(e) {
});
$("#something").on("pagebeforeshow", function(e) {
});
</script>
<div data-role="header">
</div>
<div data-role="content">
</div>
</div>
</body>

正如许多人建议使用延迟是一个好的选择,只要你不关心什么顺序deviceready和mobileinit发生.但在我的情况下,我需要一些pageshow事件,当应用程序首次加载,mobileinit并通过扩展这些pageshow/ pagebeforeshow/ etc事件是所有在deviceready完成之前解雇,所以我无法使用延迟对它们进行正确绑定.这种竞争条件不是一件好事.
我需要做的是确保'mobileinit'在' deviceready'已经被解雇之后才发生.因为mobileinit当你加载JQM时立即触发我选择jQuery.getScript用来加载它后AFTER deviceready已经完成了.
<script src="cordova-2.2.0.js"></script>
<script src="js/jquery-1.8.2.min.js"></script>
<script src="js/async.min.js"></script>
<script src="js/app.js"></script>
<script>
document.addEventListener(
'deviceready',
function () {
$('body').css('visibility', 'hidden');
$(document).one("mobileinit", function () {
app.init();
$('body').css('visibility', '');
});
$.getScript('js/jquery.mobile-1.2.0.min.js');
},
false
);
</script>
我隐藏正文的原因是,在加载jquery.mobile之前,此方法的副作用是原始HTML文档可见性的半秒.在这种情况下,隐藏它需要额外半秒的空白空间来查看未标注的文档.
